Application filed March 29, 1920. Serial no. 369,596.

To all whom it mag concern Be it known that I, W'ALKER E. MARSHALL, a citizen of the United States, and a resident of the city of Springfield, county of Clark, and State of Ohio, have invented certain new and useful Improvements in Automo-- bile Attachments a specification.

5 invention relates to new and useful Improvements in an automobile attachment, and has for its objectthe provision of adevice which will prevent the operationof an automobile without the consent of the owner. Another object is the provision in such an of which the following is attachment. forautomobiles ofv means for closing communication between-the manifold and the carburetorof the gasoline engine. 1 1 H Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described andclaime'di I I The inventionwill be best understood by reference :to "the accompanying drawings forming a part of this specification, and in which,

v Fig. 1,-is a side-elevationof agasoline engine embodying the -invention,*.

ffFig'. 7, aside elevational view of the stop used in theinvention, showing parts in section. l v s The invention is:desi'gned for use with anelevational view of the in gine 14'. The preferred form of construe .and 17. Secured tothecasing 15, and;

' 1 8 and 19, respectively, by means of which thedevi'ces maybe secured to the carbures tor 12 and the intake "pipe-13 by suitable bolts o y e in the var ous parts w gether. As shown in Fig; 4, one side-0f the casing 15 is open, and is provided with a cap 20 which serves as a closure therefor when threaded into place; The cap 20 is provided with an opening 21 "into which is threaded a cylinder or lock barrel 22in which is positioned suitable tumblers :(not shown). A disc 23'is' positioned in the open ing 21 and rests upon shoulders 23' formed therein, said disc 23 beingprovided with a suitable key slot in which a key may be inserted, which is designed for co-operation with the tumblers mounted in the drum or barrel 22. Positionedloosely in an embracs ing position upon the member 22 is a cupshaped member-2e, which is provided at its open end, with a flange 25 which restsupon the inner surface of the cap 20. Embracing the member 24, and securely fastened thereto atone end, is a spiral spring 26, the oppo site end 27 of which is secured to the cap20 by means of a pin or screw 28. Securely fastened to the base of the member 24 is an uprighteXtendingpost 29, the end which is secured to the member 2 1 having a reduced portion which extends into the interior of said member and is provided with a suitable slot 29' for engagement with the e'nd'of the 7 key used to operate the lock. The upper end of the member 29 is provided with an angularly turned arm 30, which engages in a socket 32 formed centrally on an arcuate valve disc 3L As shown, a spiral spring 33 is positioned in the socket of the member 32, so as to contact with the bottom of the'sockst, and the interior. end ofthe member 30 thereby serving to retain the member 31 in" close contact with the inner surface, of the casing 15. Threaded into the casing 115-, so as to communicate with the interior thereof, is a sleeve 3a in which is'slidably positioned a plunger 35 which, when in its normal position, projects into the interior of the casing 15, as shown in Fig. 5'. The member 35 is provided'intermediate its ends with areduced portion v36, upon which is positioned a spiral spring 37 which engages'at onefend the shoulder 35. formed onthe member 35, andthe shoulde'r 36 formed on the member-v thereby serving to retain the member 35 in its outwardlythrustfposition. The mem-- ber 35 is provided at the end exterior to the casing 15 with an enlarged portion 38, to which may be attached a suitable rod or w Wh sk m y be s d or preie ted. so a to extend above the body of the automobile with which the engine 14 is used, so that the plunger 35 may be operated from above the body of the car.

In use, the casing 15 is mounted as a lready described and as shown in Fig. 1. When the member 31, or the valve proper, is operative, one of the ports in the casing will be closed, thereby preventing the passage of any explosive fluid "from the carburetor to the manifold. In Fig. 5 I have shown the device mounted for closing the port '17. When it is desired to open the port, the key which is specially designed for each particular device, is inserted into the lock drum and the valve turned to the position shown in Fig. 5. Upon the member 31 clearing the pointat which the member projects into the casing 15, the member 35, in response to the pressure of the sprin 37, assumes the position shown in Fig 0, thereby retaining the valve member 31 in open or in-operative position. This is the position of the valve when the engine is being used. By attaching a suitable cord or other element, to the member 38, the plunger 35 may be retracted from above the body of the car and the valve 31 will then move into operative position or into such a position as to clos the port 17 the valve moving in response to the tension of the spiral spring 26. In this way, I have provided a. means whereby the owner of the car' may prevent its unlawful use, or its theft, inasmuch as the engine can not be operated until the valve 31 is moved to inoperative position. In order to do this, a

'lrey, which will co-operate with the wards mounted in the barrel 22, is necessary. The

key, not shown, when properly positioned in the barrel, engages the notch29. and by a turning movement thereof the valve 31 is rotated to an open position. As shown in Fig. 4, I have provided a pawl 39 upon the cap 20, said pawl being spring-actuated so as to spring into a notch or recess 40 formed in the inner surface of the casing 15. The member. 89 is so'positioned that the cap 20 may be secured onto the casing but cannot be turned baokwardly. I have also projected a screw 41 through the cap 20 and into the casing 15, to further insure the permanency of the connection between the cap 20 and the casing 15.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification with out departing from the spirit of the inven tion. I, therefore, do not wish to be limited to the precis details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the'appended claims.
